Cybersecurity firm FireEye said Tuesday it had been hacked by what the company called “a nation with top-tier offensive capabilities," compromising its internal software and systems, the Wall Street Journal reports.

Why it matters: The company said the attacker accessed the firm's internal tools used to test the cyber defenses of its clients and sought information about its government customers. FireEye noted it had no evidence thus far that data belonging to its clientele had been jeopardized, and it's investigating the breach with the help of the FBI and industry partners, such as Microsoft.

The incoming administration is planning extraordinary steps to protect its most prized commodity, Joe Biden, including requiring daily employee COVID tests and N95 masks at all times, according to new guidance sent to some incoming employees Tuesday.

Why it matters: The president-elect is 78 years old and therefore a high risk for the virus and its worst effects, despite having received the vaccine. While President Trump's team was nonchalant about COVID protocols — leading to several super-spreader episodes — the new rules will apply to all White House aides in "high proximity to principals."

The Department of Justice told Sen. Richard Burr (R-N.C.) on Tuesday that it will not move forward with insider trading charges against him.

Why it matters: The decision, first reported by the New York Times, effectively ends the DOJ's investigation into the senator's stock sell-off that occurred after multiple lawmakers were briefed about the coronavirus' potential economic toll. Burr subsequently stepped down as chair of the Senate Intelligence Committee.
